Composite additive applied to engine oil

[0011] Example 1

[0012] A composite additive used in engine oil, consisting of base oil; antioxidant; dispersant; detergent; corrosion inhibitor; foam inhibitor; metal deactivator; demulsifier; viscosity index improver; extreme pressure additive; oxidation Tungsten powder; molybdenum oxide powder. The base oil is composed of three components of synthetic base oil, poly-a-olefin, polyether and polyol ester; the weight ratio of the three components is 1:1:1. Antioxidant is a mixture of sterically hindered phenol and arylamine; dispersant is monobutyrimide; detergent is sulfurized calcium alkylphenate; corrosion inhibitor is substituted imidazoline; foam inhibitor is polyacrylate; metal reduction The active agent is benzotriazole; the demulsifier is polyalkoxy polyol; the viscosity index improver is styrene diene copolymer; the extreme pressure additive is alkyl phosphate ester and salt; tungsten oxide powder and molybdenum oxide powder It is a nanometer powder with a particle size
